15、ry (26) experience for raising kids. There are studies suggesting that parents are (27) happy than childless couples and single people without children. It is obvious that parents who have children to care must have much more trifles to deal with.Well, its true that over the past several years a wav

16、e of studies has (28) parenting with unhappiness. But thats not the whole story. In fact, one study by researchers at the University of British Columbia and Stanford found just the (29) . They claimed that, all things considered, parenthood is strongly associated with happiness and (30) . Specifical

17、ly, the study found that parents are happier when taking care of their kids than when doing other chores. Dads especially seemed to find happiness and meaning (31) to non-dads. They self reported to feel happy when they prepare (32) for the child or when they play games together with the child.Now,

18、of course this doesnt mean that all parents are always (33) than all non-parents. Parenting happiness depends, at least in part, on the particulars of a (34) For example, the study also found that older, married parents are on average happier than younger parents and single parents. And anyone whos

19、been a parent knows that raising kids is a tough job filled with as many difficult and painful moments as with moments of joy. But on the whole, at least according to this and other (35) studies, parenting tends to coincide with happiness and fulfillment in life.（分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:

Thus, how to stay warm, dry and safe are very important. Frostbite damages that happen when skin is exposed to extreme

21、cold for too long. It mainly happens on the hands, feet, nose and ears. People with minor cases of frostbite that affect only the skin may not suffer any (37) damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold. If blood (38) are damaged, people ca

27、填空项 1:_填空项 1:_填空项 1:_填空项 1:_十一、Section B(总题数：1，分数：71.00)Depletion of the Ogallala AquiferA) The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880s. This region has a semiarid climate, and for 50 years after its settlement, it supported a

28、 low-intensity agricultural economy of cattle ranching and wheat farming. In the early twentieth century, however, it was discovered that much of the High Plains was underlain by a huge aquifer (a rock layer containing large quantities of groundwater). This aquifer was named the Ogallala aquifer aft

29、er the Ogallala Sioux Indians, who once inhabited the region.B) The Ogallala aquifer is a sandstone formation that underlies some 583,000 square kilometers of land extending from northwestern Texas to southern South Dakota. Water from rains and melting snows has been accumulating in the Ogallala for

30、 the past 30,000 years. Estimates indicate that the aquifer contains enough water to fill Lake Huron, but unfortunately, under the semiarid climatic conditions that presently exist in the region, rates of addition to the aquifer are minimal, amounting to about half a centimeter a year.C) The first w

31、ells were drilled into the Ogallala during the drought years of the early 1930s. The ensuing rapid expansion of irrigation agriculture, especially from the 1950s onward, transformed the economy of the region. More than 100,000 wells now tap the Ogallala. Modern irrigation devices, each capable of sp

32、raying 4.5 million liters of water a day, have produced a landscape dominated by geometric patterns of circular green islands of crops. Ogallala water has enabled the High Plains region to supply significant amounts of the cotton, sorghum, wheat, and corn grown in the United States. In addition, 40

33、percent of American grain-fed beef cattle are fattened here.D) This unprecedented development of a finite groundwater resource with an almost negligible natural re-charge ratethat is, virtually no natural water source to replenish the water supplyhas caused water tables in the region to fall drastic

34、ally. In the 1930s, wells encountered plentiful water at a depth of about 15 meters; currently, they must be dug to depths of 45 to 60 meters or more. In places, the water table is declining at a rate of a meter a year, necessitating the periodic deepening of wells and the use of ever-more-powerful

35、pumps. It is estimated that at current withdrawal rates, much of the aquifer will run dry within 40 years. The situation is most critical in Texas, where the climate is driest, the greatest amount of water is being pumped, and the aquifer contains the least water. It is projected that the remaining

36、Ogallala water will, by the year 2030, support only 35 to 40 percent of the irrigated acreage in Texas that is supported in 1980.E) The reaction of farmers to the inevitable depletion of the Ogallala varies. Many have been attempting to conserve water by irrigating less frequently or by switching to

37、 crops that require less water. Other, how-ever, have adopted the philosophy that it is best to use the water while it is still economically profitable to do so and to concentrate on high-value crops such as cotton. The incentive of the farmers who wish to conserve water is reduced by their knowledg

38、e that many of their neighbors are profiting by using great amounts of water, and in the process are drawing down the entire regions water supplies.F) In the face of the upcoming water supply crisis, a number of grandiose schemes have been developed to transport vast quantities of water by canal or

39、pipeline from the Mississippi, the Missouri, or the Arkansas rivers. Unfortunately, the cost of water obtained through any of these schemes would increase pumping costs at least tenfold, making the cost of irrigated agricultural products from the region uncompetitive on the national and internationa

40、l markets. Somewhat more promising have been recent experiments for releasing capillary water (water in the soil) above the water table by injecting compressed air into the ground. Even if this process proves successful, however, it would almost triple water costs. Genetic engineering also may provi

41、de a partial solution, as new strains of drought-resistant crops continue to be developed. Whatever the final answer to the water crisis may be, it is evident that within the High Plains, irrigation water will never again be the abundant, inexpensive resource it was during the agricultural boom year

42、s of the mid-twentieth century.G) The Ogallala Aquifer is a vast, shallow underground water table aquifer located beneath the Great Plains in the United States. One of the worlds largest aquifers, it covers an area of approximately 174,000m2 (450,000km2) in portions of eight states: (South Dakota, N

43、ebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).H) It was named in 1898 by N. H. Darton from its type locality near the town of Ogallala, Nebraska. The aquifer is part of the High Plains Aquifer System, and rests on the Ogallala Formation, which is the principal geologic unit un

44、derlying 80% of the High Plains.I) About 27 percent of the irrigated land in the United States overlies the aquifer, which yields about 30 percent of the ground water used for irrigation in the United States.J) Since 1950, agricultural irrigation has reduced the saturated volume of the aquifer by an

45、 estimated 9%. Depletion is accelerating, with 3% lost between 2001 and 2008 alone.K) Certain aquifer zones are now empty; these areas will take over 100,000 years to replenish naturally through rainfall.L) The aquifer system supplies drinking water to 82 percent of the 2.3 million people (1990 cens

46、us) who live within the boundaries of the High Plains study area.M) The deposition of aquifer material dates back 2 to 6 million years, from the late Miocene to early Pliocene ages when the southern Rocky Mountains were still tectonically active.N) From the uplands to the west, rivers and streams cu

47、t channels in a generally west to east or southeast direction. Erosion of the Rockies provided alluvial and aeolian sediment that filled the ancient channels and eventually covered the entire area of the present-day aquifer, forming the water-bearing Ogallala Formation.O) In that respect, the proces

48、s is similar to those currently prevailing in other modern rivers of the area, such as the Kansas River and its tributaries. The major differences are time and depth.（分数：71.00）(1).This aquifer was named the Ogallala aquifer after the Ogallala Sioux Indians, a group of native people once inhabited the region.（分数：7.10）填空项 1:_(2).Less than
